[Chemical protection of golden hamsters against ionizing radiation]

It was shown on Golden hamsters, which are characterized by high radioresistance of the intestine, that S-2-(omega-aminopropylaminoethyl) thiophosphorous acid (gammaphos) exerts a protective action against both X- and neutron-radiation although in the latter case the protection is less pronounced. In conditions of hibernation, the protective effect of gammaphos against X-radiation was not statistically reliable. Hibernation during exposure and at the postirradiation period increases considerably the radioresistance of animals. The influence of hibernation depends upon its duration.
